The Execution &
Evidence Layer for AI
GLACIS creates cryptographic proof that your AI controls actually ran — not just that policies exist. Third-party witnessed attestations, with zero data egress.

The challenge
The Proof Gap in AI
Today, there’s no standard way to prove that AI controls actually executed. Policies describe intent. Dashboards show configuration. But neither provides independent evidence of what happened at runtime.
Documentation Isn’t Proof
Policies and procedures describe what should happen. They don’t verify what did happen when the model ran.
Observability Isn’t Evidence
Dashboards and logs are useful for debugging. But self-maintained records lack the independence needed for compliance and liability.
Attestation Closes the Gap
Independent, cryptographic proof that controls executed — witnessed by a third party, with data that never leaves your environment.
Why this matters now
When Sharp HealthCare faced a class action over their AI scribe in November 2025, the core issue was evidence: they needed to demonstrate what the AI actually did. As AI systems take on more responsibility in regulated industries, the ability to prove control execution — not just assert it — becomes essential.
How it works
Zero-Egress Attestation
You don’t need a third party to see sensitive data to prove integrity. GLACIS generates cryptographic receipts for every AI interaction — hashing prompts, responses, tool calls, and policy decisions locally, then anchoring those receipts to an independent witness network. The sensitive payload never leaves your environment.

FAQ
Common questions
We already have SOC 2 / are working toward HITRUST
Great — those cover IT controls. AI-specific assurance addresses model behavior, decision audit trails, and content safety risks that SOC 2 and HITRUST don’t cover. They’re complementary.
How is this different from our existing documentation?
Documentation describes what should happen. GLACIS provides cryptographic proof of what actually happened — third-party witnessed evidence that your controls executed, not just that policies exist.
What industries do you work with?
We work with AI teams in regulated industries including healthcare, financial services, insurance, and enterprise. The common thread is needing to prove AI controls work, not just that policies exist.
What if we’re not ready for a full compliance program?
That’s fine. We offer focused engagements for teams who need to unblock deals now. Start with what you need, expand later.
